IMPROVEMENT IN SCYTHE-SNATH FASTENINGS.

Specification forming part of Letters Patent No. 204,327, dated May 28, 1878; application filed April 23, 1878.

To all whom it may concern:

Be it known that I, MANLIUS HEWITT, of St. Louis, in the county of St. Louis and State of Missouri, have inventeda new and Improved Scythe-Snath Fastening; and I do hereby declare that the following is a full, clear, and exeXact description of the same, reference being had to the accompanying drawing, .forming part of this specification, in which- Figure 1 is a face view of the fastening devices applied to a snath. Fig. 2 is a side view with the swinging socket-plate in section and the suath partly broken away. Fig. 3 are details of the locking-bolt.

My invention relates to an improvement in that form of scythe-snath fastening in which a swinging socket-plate receives the toe of the scythe-shank, and is capable of adjustment in different positions to regulate the set or inclination of the blade.

The improvement consists in constructing the swing-socket with teeth upon the curved edge of its swinging end, and combining them with a bolt having beneath its head a corresponding set of teeth, which mesh with the teeth of the socket-plate to hold the latter rigidly in position, the socket-plate being adjusted to regulate the set of the blade by turning the bolt axially, as hereinafter more fully described.

In the drawing, A represents the lower end of a scythe-snath, upon which is arranged the metal collar B. O is an eyebolt, whose loop or eye embraces the shank of the blade D, and whose stem extends through the collar B, and is provided upon the outside with a nut, whereby the eyebolt is drawn down to clamp the shank of the blade upon the flattened face of the collar. E is the swinging socket-plate, which is pivoted near the collar at a, and is provided with a socket, b, to receive the toe c of the bladeshank, all as heretofore employed.

To obtain the varying adjustments of the swinging socket-plate to regulate the inclination of the blade in securing more or less of a shear-cut, I form upon the edge of the upper swinging end of the socket-plate a series of teeth, (1, arranged in the arc of a circle struck from the pivot on as a center, and in the snatli at this point I arrange a bolt, E. Said bolt is formed with a series of teeth, d, located just beneath its head 6, which teeth engage the teeth d of the socket-plate, and, when the head 6 is drawn down by the nutf upon the opposite side of the snath, serve to hold the plate and scythe-blade rigidly in position.

To secure a greater or less inclination of the scythe-blade, the bolt is rotated axially, which action, through the engagement of the teeth 61 (1, causes the socket-plate and the top of the shank to be thrown to one or the other side, as the case may be.

Having thus described my invention, what I claim as new is- 1. The swinging socket-plate provided with teeth or notches upon the edge of its swinging end, combined with a bolt having projections adapted to engage with said teeth or notches, substantially as described.

2. The swinging socket-plate having teeth d upon the edge of its swinging end, combined with a transverse bolt having an overlapping head, e, and teeth 01, adapted to engage with the teeth of the swinging plate and hold the same in position, substantially as described.

MAN LIUS HEWITT.
